No. The motors are different. The motors without encoders do not have a tail shaft, so without that there is no way to attached encoders after the fact. It’s a factory installation.

Why on earth are you setting the under voltage limit to 28V???!!! The motor controller is doing exactly what it is told to do. Its a 25V nominal battery. The voltage is going to drop rapidly from 29V since it is a 25V battery. Why did you change the settings and not tell us? The battery has low voltage protection, so that should not be used!…[Read more]

what are you considering discharged? the batteries are not discharged until <22V. They will drop very quickly from 28V with nominal load. The are 25.6V batteries. We have never had an issue with these batteries. We have had 1 12V one fail in 8 years. The likelihood that you have two that are no go is extremely unlikely. You need to…[Read more]

please try the other battery. if trouble continues, it may be necessary to remove the hot glue around the connection at the motor controller. sometimes if it gets real hot, the glue will seep into the connection and cause a bad connection.

possible that its a bad connection at the roboteq battery input terminal or bad ground. make sure everything is tight and clean connections.

disconnect one of the batteries. They will both read the same voltage when wired in parallel…

Hey Tyagi,

Have any modifications been made to the robot since you received it? If so, please send pictures.

I would disconnect the battery not holding a charge, and test with one battery. Let us know what the results are.

Jerome,

Here is the documentation on the SyRen Arduino library.
https://www.dimensionengineering.com/info/arduino
Unfortunately, we do not have any already written code for the SyRen to Arduino interface.

Depending on your project, have you considered using RC control? That would be a lot easier and involve less code.

No, you can’t directly trip a relay using an Arduino’s digital outputs. This is true for the majority of common microcontrollers.

We do have a few products that will let you work around this issue and drive relays using an Arduino:

– Boards with relays on them already…[Read more]

This IMU is pretty inexpensive and has adjustable gyro sensitivity: https://www.superdroidrobots.com/shop/item.aspx/minimu-9-v5-gyro-accelerometer-and-compass-lsm6ds33-and-lis3mdl-carrier/2274/

There is an Arduino library available for it and you can adjust the gyro sensitivity through the i2c registers.

I’m looking at the Arduino code now. It is set up to the read the ultrasonic sensor values and report the raw values on the Analog2 byte of the return packet. The sensor should be connected to digital pin 8 on the Arduino. Try moving your hand in front of the sensor and see if the Analog2 value changes. There is no obstacle detection or stopping…[Read more]

The checkboxes at the bottom are digital (high/low or true/false) inputs and outputs. The top row of checkboxes are inputs (values coming back from the robot) and outputs (values going to the robot). The inputs will be checked when the robot sets the values high in the return packet, and you can set the output values in the Tx packet by checking…[Read more]

The Enable Drive is only used by the WifiATR program and just allows/blocks whether it sets the drive and turn values in the packet.

If you have an older version of the code, there was a previous bug that caused an incorrect checksum value (last 2 bytes) to be shown in the Debug Window. Are the robot’s lights still blinking when you are sending a…[Read more]

I see what you mean now. If the encoders were from our motors, they will have the following configuration:
Brown – V
Green – G
Blue – B
purple – A

the encoders should fit directly into the pullup board on the 0.1″ side https://www.superdroidrobots.com/images/TE/TE-179-000-C.jpg

on the breakout board, the order is BAVG, so you will have to switch…[Read more]

the pin sizes are located on https://www.superdroidrobots.com/shop/item.aspx/ig32-ig42-and-ig52-gear-motor-encoder-pull-up-board/1512/

to connect to the roboteq, you can use https://www.superdroidrobots.com/shop/item.aspx/6-pin-molex-microfit-3-0/2280/

I assume that you have the WifiATR source code since we include that with all of our WifiATR robots. The code was built in Visual Studio 2013 so you should have the smoothest experience working with it in that environment, but it may work in newer versions as well.

Joystick values are read in the function InputTimer_Tick() and the command packet…[Read more]

Its programmable, but you have to do the programming… The code we provide is to provide basic functionality, you have to develop it from there. It’s part of the learning process. Arduino forum has lots of examples of wall following, and using the sonar, etc. you will have to merge and adjust it all to fit your use.

You can modify the source code however you wish to control the robot as needed. You can you the sonar to follow walls, etc. You can program a lot of different functions using the Arduino.

Which version of the SlimDX Runtime did you install? If you’re using a 64-bit computer you need to use the x64 installer or the WifiATR program will crash. Alternatively, if the x64 installer didn’t work then uninstall it and try the x86.
